4 Function This panel can provide mixing, distribution, and zoning for a wide variety of hydronic heating applications. The effectiveness of the system is dependant on the system being designed and installed correctly. Proper consideration of factors such as BTU loads, outdoor design temperature, indoor design temperature, room set-point temperature(s), differential fluid temperatures, head loss, flow rates, and transfer capacities of the heat emitters is critical. Once these factors have been considered and the system requirements determined, these can then be evaluated and compared to the zone control panel capabilities (refer to pages 5-0). Note: This panel does not regulate or monitor the operating safety limit temperatures of the fluid leaving the heat source. Unpacking Step Examine carton for any damage that may have occurred during shipping. If damage is visible notify your courier and supplier immediately. Step Open the carton by removing the staples. Step 3 emove the cardboard spacers from the carton, then remove the panel from the carton. Lift the panel by the base, not the enclosure.

24 Heat Link Modes of Operation The 3355 can function in three different modes of operation. ) Outdoor eset Multizone Operation Indoor temperature feedback from Thermostats by use of the external heat demand input contacts. The heat demand is activated whenever a thermostat calls for heat. Whenever the control is powered up, a heat demand is present and not in WWSD, the control operates the valve, boiler and pump to maintain an outdoor reset mix target termperature at the mix supply sensor. The oom setting allows for manual parallel shifting of the heating curve.

25 Sequence of Operation Warm Weather Shut Down Warm Weather Shut Down ( ) occurs when the outdoor air temperature is warmer than the WWSD setting (± F). If a setback schedule is selected, the control allows for two WWSD settings. If only one schedule is active, WWSD occurs with the appropriate schedule. If two schedules are active, WWSD Wake Occ occurs when either one or both of the schedules are in the Wake Sleep events; and WWSD Unocc Sleep occurs when both schedules are in the Unocc Sleep events. Whenever the control is in WWSD, the segment is displayed. Heat Demand A heat demand is required in order for operation to occur. A heat demand is present when: ) Permanent Demand DIP Switch 3 is set to Permanent Demand. or ) External Demand (DIP Switch 3 is set to external demand). Whenever a contact closure (short) is applied across the heat demand terminals (3 & 4) The icon is turned on whenever a heat demand is present. Outdoor eset Operation The control adjusts the mix target temperature with changing weather conditions using a characterized heat curve. An outdoor sensor is required. Outdoor reset adjusts the mixing valve supply water temperature to compensate for additional heat loss as the outdoor temperature falls Outdoor Air Temperature Supply Water Temperature Mixing Valve Operation Whenever the control is powered up, a heat demand is present and not in WWSD, the control provides a mixing output to an actuator which drives a mixing valve to maintain either an outdoor reset mix target temperature or setpoint mix target temperature at the mix supply sensor. Output Signal The control can provide 3 different output signals to a mixing valve actuator: ) 0:0 = 0 to 0 V (dc) analogue signal ) :0 = to 0 V (dc) analogue signal 3) Flot = 4 V (ac) floating action. The control pulses the open or close outputs to actuate the mixing valve. The 3355 control has a 5 second delay before operating the valve once a heat demand is applied. The 5 second delay is to allow the pump to circulate the water in the system and to stabilize temperatures so that the sensor does not see any temperature spikes. The time to change from closing the valve to opening the valve is dependent on the Motor Speed and the PID error difference between the mix supply sensor and the mix target. Therefore, there is no fixed time to change from close to open on the valve. 5

26 There are 8 required settings for outdoor reset operation: ) Indoor or oom Indoor Sensor Feedback The indoor setting is only available when an indoor air sensor is present. Indoor sensor feedback allows the control to compensate for internal indoor heat gains and additional heat losses such as wind loss which outdoor reset does not account for. When an indoor sensor and a permanent demand is present, the Timer and Timer contacts are disabled. Instead, there are up to four separate Indoor Target temperature settings. oom Setting (No Indoor Sensor Feedback) When an indoor air sensor is not present, the outdoor reset water temperature can be adjusted using the room setting. This provides fine tune adjustment by parallel shifting the entire heating curve. ) Outdoor Design - The Outdoor Design is the coldest annual temperature in the area. If the Outdoor Design is set to OFF, the control operates in the setpoint operation and disables outdoor reset. 3) Terminal Unit - There are 6 different terminal units. When a terminal unit is selected, the control automatically changes the mix design, the mix minimum, and the mix maximum default settings. The defaults can be changed to better match the installed system. 4) Mix Indoor - The Mix Indoor is the starting point of the characterized heating curve. This is typically set to (70 F). 5) Mix Design - The water temperature required to heat the building on the coldest day of the year. 6) Mix Minimum - The lowest mix water target temperature. 7) Mix Maximum - The highest mix water target temperature. This can be used to help prevent overheating on a radiant floor. 8) Warm Weather Shut Down - When the outdoor temperature exceeds the Warm Weather Shut Down (WWSD) setting, the heating system is shut down by closing the mixing valve.

27 Setpoint Operation The control can operate the mixing valve to maintain a fixed setpoint outlet temperature. To enter the setpoint mix target temperature: Press the Menu Press the Item and set to OFF. button to enter the menu. button to find Outdoor Design Press the Item button to find Mix Target and set the mixing valve outlet temperature. Boiler Output Output Signal The control operates the boiler relay as a boiler enable. The Boiler ON setting allows the adjustment of the boiler enable point as the mixing valve is opened (default of 5%). The Boiler OFF setting allows the adjustment of the boiler shut off point as the mixing valve is closed (default of 5%). The boiler contact has a 3 minute minimum on time regardless if heat demand is removed. The pump is on while the boiler contact is on. Once the demand is removed, the mixing valve is closed. The minimum off time for the boiler relay is 0 seconds. Warning: The boiler minimum on time can cause the dead heading of the pump if no bypass or continuous flow loops are present. Motor Speed The control requires the motor speed time to operate the mixing valve from fully closed to fully open. The default value of 50s is the proper setting for the HeatLink 56 DD actuator and 5800 series mixing valve motors. Pump Operation The control includes a powered boiler pump. When the DIP switch is set to permanent heat demand, the pump runs continuously except when control is in WWSD. When the DIP switch is set to external heat demand, the pump only operates when an external heat demand is applied and the control is not in WWSD. The pump symbol is shown while in the View menu and the pump is operating. Once the heat demand is removed, the pump continues to operate for the time set by the pump purge setting. During the pump purge, the pump symbol flashes while in the View menu. Exercising The control includes a feature which exercises the system pump and mixing valve in order to prevent corrosion and precipitate build-up due to prolonged periods of inactivity. If the pump has not run in the past 3 days, the pump will run for 0 seconds. If the mixing valve has not operated its full stroke in the past 3 days, the control will operate the valve to the fully open position and then back to the fully closed position. TEST will be displayed during exercising and can be exited by pressing the down Setting the Time SHD button. The control has an internal time clock. The time is maintained for at least 4 hours in the case of power loss. The time is visible in the TIME menu only when DIP switch is set to setback. To set the time: ) Press and release the Menu button until the TIME menu is found. ) Press and release the Item button. The minute numbers will flash. Press the up or down button to set the minutes. 3) Press and release the Item button. The hour number will flash. Press the up or down button to set the hour. 4) Press and release the Item button. The day of the week number will flash. Press the up button to set the day of the week. Night Setback or down The control can also operate either one or two night setback channels. The night setback operates by opening or closing the timer relay contact or the timer relay contact at the event time. This causes thermostats to operate at their night setback temperature. When an indoor sensor and a permanent demand is present, the Timer and Timer contacts are disabled. Instead, there are up to four separate Indoor Target temperature settings. When the control is in single zone operation (emote indoor sensor connected and DIP set to permanent demand), only channel setback program is available. The channel setback program is not shown and the control operates both the channel relay and the channel relay at the same time. The second night setback channel SHD can be set to one of three settings: ) P = schedule copies schedule event times. ) On = setback schedule is on and separate from schedule. 3) OFF = setback schedule is off. 7

28 Manual Override Select a manual override to prevent the scheduled event from happening. OFF = operate on scheduled night setback. This is the default setting. Temporary Wake = temporarily operate at the Indoor Target Wake temperature or close the timer contact for 3 hours. Permanent Wake = permanently operate at the Indoor Target Wake temperature or close the timer contact. Temporary Unoccupied = temporarily operate at the Indoor Target Unoccupied temperature or close the timer contact for 3 hours. Permanent Unoccupied = permanently operate at the Indoor Target Unoccupied temperature or close the timer contact. Temporary Occupied = temporarily operate at the Indoor Target Occupied temperature or close the timer contact for 3 hours. Permanent Occupied = permanently operate at the Indoor Target Occupied temperature or close the timer contact. Temporary Sleep = temporarily operate at the Indoor Target Sleep temperature or close the timer contact for 3 hours. Permanent Sleep = permanently operate at the Indoor Target Sleep temperature or close the timer contact. Away = operate the indoor target at 7.0 (6.5 F) or close the timer contact. When using outdoor reset, the warm weather shut down occurs at 7.0 (6.5 ). MODE Select how many night setback events should occur each day. OFF = no night setback = setback events per day:, 4 = 4 setback events per day:,,, TYPE For each scheduled setback event, a time between 00:00 and 3:50 must be set. If it is desired to skip the scheduled setback event, set the event time to :. : is found between 3:50 and 00:00. Temporary Override When an indoor sensor is present, the desired indoor temperature can be temporarily overridden by pressing the up or down button. The temporary override remains in effect for 3 hours. To cancel the temporary override, press and hold the up and down SHD TYPE buttons together. Tmpy SHD MODE Select the type of repeating schedule. 4 hr = schedule repeats every 4 hours. 5- = schedule repeats every week. The 5 weekdays event times are grouped together. Saturday and Sunday have separate event times. 7dAY = schedule repeats every week. There are separate event times for each day. Setting Event Times 8
